WINDOW-SASH.

Specification of Letters Patent.

Patented Jan. 10, 1911.

Application filed May 27, 1910. Serial No. 563,764.

To all whom it may concern:

Be it known that I, FRANK citizen of the United States, Salem, in thecounty of Marion and State of Oregon, have invented certain new anduseful Improvements in Window-Sash; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use the same.

lWIy invention relates to window sashes and particularly to theconstruction of the connection or joints between the sash bars ormullions.

My object is to simplify the construction of these joints whereby lesstime will be required to make window sashes and the cost of manufacturethereof will be reduced.

Other objects will become apparent from the following description.

It is my aim to obviate mortising and tenoning the bars or mullions ofthe sash as is now usually done. I propose to connect these bars bysimply boring one or more holes in the molding of the horizontal bars tofit the ends of the sections of the vertical bars which are cut offsquare. These holes are only bored down to the surface of the barproper, that is to the base of the molding, so that it is not necessaryto form tenons on the ends of the bars which fit in said holes. Themoldings on said bars are made either round or oval in cross section inorder that the ends of the vertical bars will fit into the holes boredin the horizontal bars. Because of the rounded form of the molding andthe holes or sockets into which they fit, my new connection retains thebars from moving eitlier way, that is vertically or horizontally, justas effectively as the old mortise and tenon joints.

The invention also consists in the features of construction andcombinations of parts hereinafter described and specified in the claims.

In the accompanying drawing: Figure 1 is an elevation of a portion of awindow frame constructed in accordance with my invention. Fig. 2 is asectional view on the line w0c of Fig. 1. Fig. 3 is a sectional view onthe line Q/--:I/ of Fig. 1. Fig. 4 is a detailed View of a portion ofone of the horizontal sash bars. Fig. 5 is a similar View of one of thesections of the vertical sash bar, and Figs. 6 and 7 are similar viewsM. BnowN, a

residing at of a horizontal bar and section of vertical bar of amodified construction.

Referring more particularly to Figs. 1 to 5, inclusive, of the drawing,1 and 2 designate respectively one of the stiles and one of the rails ofa sash which may be connected together in any suitable manner. Each ofthese pieces is provided with a rounded molding 3 having round holes 4:bored therein at suitable intervals to receive the ends of the bars ormullions. The horizontal bars or mullions 5 extend entirely across thesash while the vertical bars 6 are made in sections of suitable lengthto fit between the horizontal bars. It will be understood, of course,that this arrangement may be reversed and the horizontal bars made insections and the vertical bars made continuous, if desired. The moldings7 on said bars or mullions are also rounded. Round holes 8 are bored inthe moldings of the horizontal bars to receive the ends of the sectionsof the vertical bars. It will be noted that these holes are of greaterdiameter than the molding so that openings 9 are left at either sidethereof through which the ribs 10 and 11 project. It will be understood,of course, that said ribs 10 and 11 extend into the planes of the innerand outer faces of the sash respectively, the outer ribs 11 being longerthan the inner ones in order to receive the panes of glass 12 and theputty 18 which secures the latter in place. The bars are rounded incross section where the moldings are formed on the opposite sidesthereof. As illustrated in Fig. 41, the holes bored to receive the endsof the bars are round and may be formed by one operation of a boringtool. If desired, however, the bars may be oval-shaped at the pointswhere the moldings are formed and the holes to receive them may becorrespondingly oval-shaped, as illustrated at 1 1 and 15 respectivelyin Figs. 6 and 7. These oval-shaped holes 15 may be readily formed byboring two or more round holes side by side. The oval-shaped sash bar istherefore suitable for any thickness of sash, the oval being lengthenedor shortened as desired to conform to the thickness of the sash.

The simplicity of applicants connection or joint and the greatly reducedexpense re quired to manufacture it. will be readily appreciated bythose skilled in this art. No special machine is required for formingthe parts of the joint, as is necessary in making ion the mortise andtenon joints. All that is needed in order to connect my sash bars is onordinary brace and bit or other suitable boring tool for forming theholes in the molding to receive the squared off ends of the bars.

I am aware that the end of one sash bar has heretofore been grooved outto fit over the molding on another but it was then necessary t.o use atenon on the end of the grooved bar fitting into a mortise in the otherbar to secure the latter against longitudinal movement with respect tothe former. My construction retains the bars against movement in eitherdirection with out requiring a mortise or tenon and is, therefore, muchcheaper to manufacture as well as simpler in construction.

I claim 1. In a window sash, the combination, with a bar having raisedmoldings on its faces and holes formed in said moldings extending to thebases thereof, respectively, said holes being broader at the interior ofsaid moldings than at the edges thereof, of another bar arranged atright angles to the first bar and made in sections having squared offends, the adjacent ends of said sections being fitted in the holes inthe moldings of said first bar.

2. In a window sash, the combination, with a bar having rounded moldingson its faces, and rounded holes formed in said moldings extending to thebases thereof, respectively, of another bar arranged at right angles tothe first bar and made in sections having squared off ends, the adjacentends of said sections being fitted in the holes in the moldings of saidfirst bar.

3. In a window sash, the combination, with a bar having raised moldingson its faces with projecting ribs extending in opposite directions, thesaid moldings having holes formed therein extending to the bases thereofand flush with said ribs of another bar of similar shape but made insect-ions having their ends squared off, the adjacent ends of saidsections being fitted in the holes in the moldings of the first bar withtheir ribs extending beyond said holes into the planes of the ribs onsaid first bar.

at. In a window sash, the combination, with a bar having roundedmoldings on its faces with projecting ribs extending in oppositedirections, the said moldings having holes formed therein extending tothe bases thereof and flush with said ribs, of another bar of similarshape but made in sections having their ends squared ofi, the adjacentends of said sections being fitted in the holes in the moldings of thefirst bar with their ribs extending beyond said holes into the planes ofthe ribs on said first bar.

5. In a window sash, the combination, with a bar having rounded moldingson its faces, and oval-shaped holes formed in said moldings extending tothe bases thereof, respectively, of another bar arranged at right anglesto the first bar and made in sections having squared off ends, theadjacent ends of said sections being fitted in the holes in the moldingsof said first bar.

In testimony whereof, I affix my signature, in presence of twowitnesses.
